Convert AVIF to PNG

Open AVIF images anywhere by saving them as PNG, with transparency intact. The conversion runs in your browser.

Shape

Changing a setting converts every image again. Resizing keeps the proportions, and smaller images are never enlarged.

Why convert AVIF to PNG?

AVIF is a newer format built on the AV1 video codec. Websites use it because the files are small, but many desktop editors, office apps and upload forms still can't open it. PNG works everywhere and keeps transparency.

Your browser needs to be able to decode AVIF for this to work. Current Chrome, Edge, Firefox and Safari (version 16 and later) all can. As with any PNG, a photograph will be much larger than the AVIF it came from.

This is one photograph, not a general rule: flat graphics, text and transparency compress differently. The converter on this page uses your browser's encoder, so its files will be close to these but not identical.

Questions

Why won't my computer open AVIF files?
Support arrived in browsers first. Older operating systems and many editors don't include an AVIF decoder yet, so converting to PNG or JPG is the quickest fix.
My AVIF file won't convert. Why?
Your browser has to decode it. Update to a current version of Chrome, Edge, Firefox or Safari 16+. Animated AVIF sequences and HEIC photos aren't supported.
Are my images uploaded anywhere?
No. The file is decoded and re-encoded by your browser on your device, and the converted copy is handed straight back to you. Nothing is sent to Img9 or anyone else, so the page also works offline once it has loaded.
Is there a file size or count limit?
There is no account and no daily limit. The practical limit is your device's memory: very large images, roughly 50 megapixels and up, can fail in some browsers, and phones hit that sooner. Set a maximum width to make big photos smaller as they convert.
